I'm not a Kindle user, but I was pleased to see that Henry George's book, Progress and Poverty: An Inquiry into the Cause of Industrial Depressions and of Increase of Want with Increase of Wealth, The Remedy is available for Kindle, for under $4. See http://www.amazon.com/Progress-and-Poverty-ebook/dp/B002BU24PQ/ref=sr_1_5?ie=UTF8&s=digital-text&qid=1263678914&sr=8-5
I wish, however, that Bob Drake's 2006 abridgment, Progress and Poverty: Why there are recessions and poverty amid plenty -- and what to do about it!, a thought-by-thought updating of Henry George's much longer original -- was also available as for Kindle.
You can also read either of them online. The original unabridged is at http://schalkenbach.org/ and Drake's abridgment at http://www.progressandpoverty.org/ and also at http://henrygeorge.org/ (the latter has an excellent online course and related materials). And you can download MP3's of Drake's abridgment at http://hgchicago.org/audio/.
I encourage you to explore that last website, for the Henry George School of Chicago, including the page which starts this way:
Why Not Enroll?
Which of the reasons below prevents you from enrolling?
and proceeds to list 7 "reasons" one might propose. Here's the first one:
1. George's ideas may have been important in the 19th century, but today we're in an information economy, land doesn't really matter, and besides, poverty really isn't much of a problem anymore. George described fundamental principles that always apply as long as people need a place to live and don't want to work for nothing. Sure, the economy has changed, but land remains extremely important. Ask anyone struggling to remain in a gentrifying neighborhood. Poverty no longer a problem? Worldwide, by any measure, billions of people remain in poverty. In the U. S., few of us starve but many of us suffer from high cost of living, low wages, and poor working conditions. Why should supporting a family require both parents to have full-time employment? Why should people have to commute an hour or more from areas with affordable housing to areas with decent jobs? These thoroughly modern problems are clearly analyzed in our courses.
